Item 7.01. Regulation FD Disclosure.

On December 2, 2004, Ruben S. Martin, President and Chief Executive Officer, and Scott Martin, a Director, respectively, of the general partner of Martin Midstream Partners (“the Partnership”), made a presentation concerning the Partnership’s financial performance, strategy and outlook at the 4th Annual 2004 Louisiana Energy Conference held at the Windsor Court Hotel in New Orleans, Louisiana. The Partnership’s presentation at the conference was webcast live with an accompanying slideshow on the Partnership’s website. Attached as Exhibit 99.1 are the slides presented during that presentation and on the Partnership’s website.

In accordance with General Instruction B.2 of Form 8-K, the information set forth in this Item 7.01 and in the attached Exhibit shall be deemed to be “furnished” and not be deemed to be “filed” for purposes of Section 18 of the Securities and Exchange Act of 1934, as amended (the “Exchange Act”).

Statements about the Partnership’s outlook and all other statements contained in the Exhibit other than historical facts are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements and all references to financial estimates rely on a number of assumptions concerning future events and are subject to a number of uncertainties and other factors, many of which are outside its control, which could cause actual results to differ materially from such statements. While the Partnership believes that the assumptions concerning future events are reasonable, it cautions that there are inherent difficulties in anticipating or predicting certain important factors. A discussion of these factors, including risks and uncertainties, is set forth in the Partnership’s annual and quarterly reports filed from time to time with the Securities and Exchange Commission. The Partnership disclaims any intention or obligation to revise any forward-looking statements, including financial estimates, whether as a result of new information, future events, or otherwise.
